Abstract
The utility model relates to a turn up bladder for a tire tri-drum building machine, which comprises a bladder and is innovatively characterized in that a concave annular groove is formed in the position where the tail end of the outer surface of the bladder is in contact with the tire bead of a green tire, and the cross section of the annular groove takes the shape of an inverted trapezoid. The turn up bladder has the advantages that since the cross section of the annular groove takes the shape of the inverted trapezoid, a traveler is sleeved on the upper edge of the inverted trapezoid of the annular groove on the bladder, and the traveler is less prone to displacement after the bladder is inflated, the building quality of the green tire is ensured, and the scrappage of the green tire is low.
Description
Technical field
The utility model relates to a kind of tire three-drum forming machine reverse-wrapped capsule, particularly a kind of wire loop accurate positioning, the tire three-drum forming machine reverse-wrapped capsule that green tire tire pin problem is few.
Background technology
The tire three-drum forming machine is the visual plant during engineering radial-type tyre is produced, the contact position of its reverse-wrapped capsule and green tire tire pin is " W " type that caves in, during the green tire moulding, wire loop is enclosed within the middle peak of " W " type that caves in, expanding in capsule inflation back, easily causes the skew of tire pin, and the wire loop location is inaccurate, green tire tire pin place symptom is more, and green tire easily causes to be scrapped.
The utility model content
The technical problems to be solved in the utility model provides a kind of wire loop accurate positioning, tire three-drum forming machine reverse-wrapped capsule that green tire tire pin problem is few.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of tire three-drum forming machine reverse-wrapped capsule, comprise capsule, its innovative point is: the terminal contact position with green tire tire pin of described capsule outer surface is provided with the cannelure that caves in, and the cross section of described cannelure is for trapezoidal.
Advantage of the present utility model is: the cross section of cannelure is for trapezoidal, and the cannelure that wire loop is enclosed within capsule falls on the trapezoidal upper base, and wire loop is difficult for displacement behind the capsule inflation, guarantees the Forming Quality of green tire, and the green tire scrappage is low.
Description of drawings
Accompanying drawing is the utility model tire three-drum forming machine reverse-wrapped capsule structural representation.
The specific embodiment
As shown in drawings, the utility model relates to a kind of wire loop accurate positioning, tire three-drum forming machine reverse-wrapped capsule that green tire tire pin problem is few, comprise capsule 1, be provided with the cannelure 2 that caves in the terminal contact position with green tire tire pin of capsule 1 outer surface, the cross section of cannelure 2 is for trapezoidal.
During use, make wire loop be enclosed within the cannelure 2 of capsule 1, be close to the trapezoidal top of going up of falling of cannelure 2, wire loop is difficult for displacement behind capsule 1 inflation, guarantees the Forming Quality of green tire.
Claims (1)
1. a tire three-drum forming machine reverse-wrapped capsule comprises capsule, it is characterized in that: the terminal contact position with green tire tire pin of described capsule outer surface is provided with the cannelure that caves in, and the cross section of described cannelure is for trapezoidal.
